LM105/LM305/LM305A
Voltage Regulators
General Description
The LM105 series are positive voltage regulators similar to
the LM100, except that an extra gain stage has been added
for improved regulation.Aredesign of the biasing circuitry re-
moves any minimum load current requirement and at the
same time reduces standby current drain, permitting higher
voltage operation. They are direct, plug-in replacements for
the LM100 in both linear and switching regulator circuits with
output voltages greater than 4.5V. Important characteristics
of the circuits are:
Output voltage adjustable from 4.5V to 40V
Output currents in excess of 10A possible by adding ex-
ternal transistors
Load regulation better than 0.1%, full load with current
limiting
DC line regulation guaranteed at 0.03%/V
Ripple rejection on 0.01%V
45 mA output current without external pass transistor
(LM305A)
Like the LM100, they also feature fast response to both load
and line transients, freedom from oscillations with varying re-
sistive and reactive loads and the ability to start reliably on
any load within rating. The circuits are built on a single silicon
chip and are supplied in a TO-99 metal can.
